Android----------属性动画

注：属性动画主要用到的类是 ObjectAnimator  一般单个动画用到的方法主要是   .setDuration();     .start();

综合的要用到 AnimatorSet类  把各个效果结合在一起的方法：

animatorSet.play(rotate).with(alpha).after(translation);

上代码：

public class MainActivity extends AppCompatActivity {
    private TextView tv;
    private Button start;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        tv=(TextView)findViewById(R.id.text_view);
        start=(Button)findViewById(R.id.start);
        start.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
              // tv.setBackgroundColor(Color.YELLOW);
                //设置属性动画的颜色
              //  ObjectAnimator  animation=ObjectAnimator.ofArgb(tv,"BackgroundColor",Color.RED,Color.GREEN,Color.BLUE);
                //平移
              //  ObjectAnimator  animation=ObjectAnimator.ofFloat(tv,"translationX",0,200);
                //渐变
               // ObjectAnimator  animation=ObjectAnimator.ofFloat(tv,"alpha",1.0f,0.0f);
                //旋转
              /*  ObjectAnimator  animation=ObjectAnimator.ofFloat(tv,"rotation",0,360);
                animation.setDuration(5000);
                animation.start();*/

               //属性动画综合
                //平移
                ObjectAnimator translation=ObjectAnimator.ofFloat(tv,"translationX",0,200);
                //渐变
               ObjectAnimator alpha=ObjectAnimator.ofFloat(tv,"alpha",1.0f,0.0f,1.0f,0.0f);
                //旋转
                ObjectAnimator rotate=ObjectAnimator.ofFloat(tv,"rotation",0,360);
                AnimatorSet animatorSet=new AnimatorSet();
                animatorSet.setDuration(5000);
                animatorSet.play(rotate).with(alpha).after(translation);
                animatorSet.start();

            }
        });

    }
}
